The 3 materials needed for photosynthesis are water, carbon dioxide, and sunlight. These 3 materials combined enable the plant to make a sugary substance known as glucose. 6 molecules of water+6 molecules of carbon dioxide=1 molecule of sugar+6 molecules of oxygen* *=The plant doesn't need the oxygen so it releases it into the air. That's how we get our oxygen. :)
